Steca PR

The Steca PR 0303 and PR 0505 solar charge

controllers are optimally suited for use in small solar

home systems with module currents up to 5 A.

A 75 Wp module can be connected, which easily allows

operation of lamps, radios and a small television.

All loads can be switched off using the manual load

switch on the controller.The extremely low own

consumption makes the Steca PR especially suitable

for professional applications in telecommunications

and traffic management technology. Since this is a

serial controller, it is extremely flexible in the type of

power source that can be connected. The electronic

fuse makes the controller completely maintenance-free

and robust.

Steca Solsum F

The Steca Solsum F-Line continues the huge success of one of the most

used SHS controllers. With a power range of up to 10 A at automatically

recognized 12 V or 24 V it fits to a system sizes of maximum 240 W.

The circuit board is completely electronically protected and with the

LED user interface it is easy to check the battery state of charge at any

time. Large terminals guarantee a simple connection of solar panels,

battery and load. The Steca Solsum F works on PWM as a low loss series

controller.

Steca Solarix PRS

The simplicity and high performance of the Steca Solarix PRS solar

charge controller make it particularly appealing. At the same time, it

offers a modern design and a convenient display, all at an extremely

attractive price.Several LEDs in various colours emulate a tank display,

which gives information on the battery‘s state of charge. Here,

Steca’s latest algorithms are employed, resulting in optimal battery

maintenance. The Solarix PRS charge controllers are equipped with an

electronic fuse, thus making optimal protection possible. They operate

on the serial principle, and separate the solar module from the battery

in order to protect it against overcharging.For larger projects, the

charge controllers can also be equipped

with special functions: e.g. with night light function and selectable

charging plateau and deep-discharge protection voltages.

Steca PR

The Steca PR 10-30 series of charge controllers is the highlight in the range.

The latest charging technologies, combined with a Steca-AtonIC state of charge

determination which has been significantly improved once again, result in optimal

battery maintenance and control of the module output of up to 900 Wp which can

be connected to it. A large display informs the user about all operating modes

with the aid of symbols. The state of charge is represented visually in the form of

a tank

display. Data such as voltage, current and state of charge can also be displayed

digitally as figures on the display. In addition, the controller has an energy meter

which can be reset

Steca Tarom

The Steca Tarom is a solar charge controller specifically designed for use in

telecommunications applications or in hybrid photovoltaic systems.Numerous clever

functions allow the user to adjust the controller to the particular features of the

system in question.

Thanks to the significantly improved state of charge determination,the system

is optimally controlled and batteries are protected. The Steca Tarom charge

controller is the best choice for system sizes of up to 2400 Wp at three voltage

levels (12 V, 24 V, 48 V).There is the option of connecting additional devices such

as a temperature sensor, a data logger and a remote control for configuring and

monitoring the system. An integrated

Ah meter also provides the

user with information on the

energy budget of the

application.

235, 245, 440

The Steca PA Tarcom data logger is connected to

the RJ45 interface of the Steca Tarom or Power

Tarom charge controller, or via the Steca PA

HS200.

The data logger is available in several different

versions: as a simple RS232 interface to directly

save and read data on the PC or Laptop (Steca PA

Tarcom 01), as a data logger with an integrated

analogue modem (Steca PA Tarcom RM), as a data

logger with an optional telephone connection

(Steca PA Tarcom RMT) and as a data logger with

an integrated GSM modem for remote monitoring

(Steca PA Tarcom GSM). The Steca PA Tarcom is

delivered with its accompanying software.

The Steca PA HS200 is a highly intelligent current sensor with

extremely low own consumption.

The Steca PA HS200 comes into play when (e.g.) an inverter is directly

connected to the battery and the Steca Tarom or Power Tarom charge

controller cannot measure the current consumption. A shunt is also

required when an additional generator (e.g. PV, wind or diesel) directly

charges the battery without being connected to a Steca Tarom charge

controller. The current is measured contact-free via a Hall-effect

sensor. The data is transmitted to the charge controller over a cable

connection. Up to two Steca PA HS200 shunts can be connected and the

measured currents can be selectively added to the charging current,

battery current or load current as desired.

Steca Power Tarom

Specially designed for industrial and outdoor

applications, the Steca Power Tarom comes with

an IP 65 casing made of powder-coated steel. This

solar charge controller can be used to control

system sizes of up to 8400 Wp at three voltage

levels (12 V, 24 V, 48V). The Steca Power Tarom

is based on the technology of the Steca Tarom

controller. When connected in parallel, several

controllers from this series can be operated via a

standard DC bus in a simple solar home system or

a hybrid system. This allows an output of over 20

kWp to be reached.
